Whether you are completely new to hiking or just beginning to explore bigger challenges, here is what the National Three Peaks actually involves and what you should know before deciding to take it on.

What is the National Three Peaks Challenge?

Traditionally, participants aim to complete all three of the highest summits in Scotland, England and Wales within 24 hours, including driving time between locations.

Why the National Three Peaks Challenge is a great option for fundraising

The National Three Peaks Challenge has a simple appeal. Climb the highest peaks in Scotland, England and Wales within 24 hours. It feels like a clear, memorable milestone, and one that works well for fundraising and sharing. There are multiple points where you can share the progress (and the pain) with sponsors as you plan and carry out the challenge.

But what you see online rarely shows the full picture. Completing all three peaks in a day means long drives, very little rest and sustained effort on tired legs.

Behind every successful attempt is careful planning, solid navigation skills and a strong focus on safety. Many people choose to take part with experienced guides to help manage the route and changing conditions.

Key things to understand about the National Three Peaks Challenge

Total driving distance is over 450 miles

Sleep is extremely limited

Much of the challenge happens in darkness or fatigue

Advanced navigation skills are essential (or employment of a professional guide)

This is not just a hike. It is an endurance event.

How difficult is The National Three Peaks Challenge really?

For beginners, the biggest surprise is how cumulative the challenge is.

It is not just three climbs. It is:

Climbing while tired

Navigating in low visibility

Sitting in a car for hours between efforts

Starting the next mountain before fully recovering

Even strong walkers find it demanding.

What beginners trying this hiking challenge often underestimate

You’ll need a team
Doing this alone is dangerous as you want to be resting on the car journey’s between each mountain. Having a team or employing a guide is the safest way to attempt this challenge.

Navigation
Many routes are not signposted. In poor visibility, paths can disappear.

Fatigue
Tiredness affects decision making, pacing and safety.

Mountain weather
Conditions on the summit can be dramatically different from the car park.

Timing pressure
The 24 hour target can lead people to rush or ignore warning signs.

Starting from scratch: steps to build up to the Three Peaks Challenge

If you are new to hiking, this step by step checklist will help you build confidence gradually before taking on the National Three Peaks.

Start with short, local walks on easy, waymarked routes to get comfortable spending time outdoors.

Learn basic navigation skills, including map symbols, paths and contour lines, and begin using OS Maps to follow simple routes.

Build up to longer walks by increasing distance, time on your feet and introducing gentle hills.

Try your first hill or small peak using a clear, mapped route in a national park.

Practice walking in different conditions, including light rain, wind or low light, to build confidence.

Plan to tackle at least one 3000ft mountain to see how your fitness levels cope.

Take on a full days walking, or try a smaller challenge such as the Yorkshire 3 Peaks

Plan the full Three Peaks Challenge, including transport, timing, rest and whether to go with a guide.

On the day, be ready to adapt your plans and prioritise safety over completing it within 24 hours.

Choosing a Three Peaks guide: quick checklist

If you are thinking about taking on the challenge with support, use this checklist to choose a safe and reputable guide:

Relevant qualifications
Look for a Mountain Leader (ML) or higher. This shows they are trained to lead groups in UK mountain terrain.

Experience on all three peaks
The challenge is not just about fitness. Local knowledge and experience in different conditions matter.

Clear safety approach
They should talk openly about pacing, weather decisions and when they would turn back if needed.

Navigation skills, not just following others
Your guide or challenge leader (if not a qualified professional) should be confident navigating in poor visibility.

Proper insurance
Check they have public liability insurance and operate professionally.

Small group sizes
Smaller groups are easier to manage safely, especially on busy or complex terrain.

Realistic expectations
Be cautious of anyone promising guaranteed 24 hour success. A good guide prioritises safety over speed.

Transparent logistics
If transport is included, check how rest, driving and timing are managed. Do they have designated drivers for each section?
